Passing an object as attribute to compiled directive on the fly - angularjs

Question

I have a angular element on the page which needs to communicate with the rest of the non angular page elements.
I am creating directive elements on the fly, and appending it to its target div. I am trying to pass that created directive an object (ajax object), which contains just attributes.
The issue is that I can't figure out how to pass just this ajax object to the directive, as $compile requires a scope. When the http finishes, and because i have to use = in the directive, the directives are being over-ridden.
Please see my plunk: https://plnkr.co/edit/brTWgUWTotI44tECZXlQ ( sorry about the images ). Click the <button> to trigger the directive.
(function() {
'use strict';
var CHANNEL = 'podOverlay';
angular.module('CavernUI', [])
.controller('CavernCtrl', function($scope,getItemService) {
$scope.model = {};
var _pods = $scope.model.pods = {};
function getData(selector) {
$(selector).each(function(i, pod) {
_pods[+pod.dataset.item] = {
$: $(pod)
};
});
Object.keys($scope.model.pods).map(function(key) {
getItemService.getItem(key).success(function(response) {
_pods[key] = angular.extend(_pods[key], response);
$scope.$broadcast(CHANNEL, _pods[key], $scope);
});
})
}
$scope.runPodCheck = function(selector) {
getData(selector);
}
})
.directive('podchecker', function($compile) {
var createOverlay = function(e,data,scope){
scope.data = data;
// can i just pass data rather than scope.data?
// If I pass the scope, then when another $broadcast happens
// the scope updates, wiping out the last scope change.
// Scope here really needs to be a static object that's
// created purely for the hand off. But I don't know if
// that can be done.
angular.element(data.$[0]).empty().append($compile('<overlay data="data"></overlay>')(scope));
}
return {
restrict: 'E',
scope: {
check: '&',
},
templateUrl: 'tpl.html',
link: function(scope,elm,attr){
scope.$on(CHANNEL,createOverlay);
}
};
})
.directive('overlay', function() {
return {
restrict: 'E',
scope: {
o: '=data' // here is the problem.
},
template: '<div class="overlay"><img ng-src="{{o.images.IT[0]}}"/></div>',
link: function(scope, elm, attr) {
}
}
})
.service('getItemService', ['$http', function($http) {
this.getItem = function(itemId) {
return $http({
method: 'GET',
url: 'https://www.aussiebum.com/ajaxproc/item',
params: {
id: itemId,
ajxop: 1
},
});
};
}]);
}());

I'm not sure this is the best approach, but one way might be to manually create a new scope for each of the overlays.
So changed this:
var createOverlay = function(e,data,scope){
scope.data = data;
angular.element(data.$[0]).empty().append($compile('<overlay data="data"></overlay>')(scope));
}
to this:
var createOverlay = function(e,data,scope){
var overlayScope = scope.$new(false); // use true here for isolate scope, false to inherit from parent
overlayScope.data = data;
angular.element(data.$[0]).empty().append($compile('<overlay data="data"></overlay>')(overlayScope));
}
